Yeah if only there weren't a dozen different international definitions of cup ranging from 100ml to 250ml

30+ years satellites, we are all metric. But as @FuglyDuck said it was a mixed team that mixed measurements that caused the failure.

We do everything in house so when parts\waveguide\antenna's\etc all gets ordered its all metric.

And I do agree 10+ years ago it was a nightmare to source but since we are international we could have bulk sent over from Europe and eventually Canada.

Oh I missed the "The worst of both worlds" part LOL I can imagine, I guess if it comes to modules they could be mixed as long as they can fit in the footprint of the engineering drawings :)

Can I hijack this to complain about small town newspapers that don't specify the state? There are 88 cities, states, counties, or districts named "Washington". Is it so hard to clear up which one youre talking about?

How would you know their location?

However, in modern recipes, the US legal cup of 240 ml (about 8.45 British imperial fluid ounces or 8.12 US customary fluid ounces) is more commonly used.

A lot of duel dimensioned drawings when you are interfacing.

I just have to be able to convert back and forth, sometimes in a single sentence: "we are using a 500mm X 450mm base made from 1/16" sheet metal."

I like how you just pulled that sentence out of context from the description for ONE country and ignored the dozen other countries with different measurements.

...
You literally pulled up a cherry picked list of where there are discrepancies. You're allowed to and im not?

Also, would you look at that: almost all of them have converged to US customary or 250mL, which is within the tolerance for error.

Yeah I've been here, in the US so getting raw stock in metric is prohibitively expensive. So sheet metal is where it all falls down and makes me a bit of a fibber. We would convert it to mm for the final drawings.

Before CNC's were common I can tell you some horror stories going to a local machine shop needing it all in metric and you could hear the modem noises in their heads. We would bring them metric micrometers and scientific rulers to help them along. Mind you this was in the late 90's and they were masters of their art, but metric wasn't the norm in their world.

The entire point of this thread from the comment you replied to, is that 'cup' is an inexact unit of measurement that varies. My list is providing examples, I'm not seeing the issue here.

You're allowed to and im not?

You were misrepresenting the statement as if it applied globally when in actuality it was meant for ONE country. That's just bad faith discussion.

Also, would you look at that: almost all of them have converged to US customary or 250mL, which is within the tolerance for error.

Except for Latin America, the UK, most of Asia, parts of Europe, etc. 🙄

Damn. You guys should stop using cups if it's that bad 😬

I saw an article where it was like, Washington on fire!

And I immediately thought we had another Jan 6 attack with MAGA terrorists. Nope. Just climate change setting the forests on fire in Washington state.
